Zfp932 is a potential mammalian functional ortholog of the zebrafish blf and drl cluster genes. (A) qPCR of the erythroid marker gene hbae1 and the neutrophil marker gene mpx in blf−/−; drl 4KO embryos after injection of human or mouse mRNA. Data are mean±s.e.m. of at least three replicates. **P<0.01. (B) Left: Expression of hbae1 in 23 hpf embryos; n=27, 32 and 29 for each experimental set. Middle: Whole-mount o-dianisidine staining of 36 hpf embryos; n=31, 39 and 33 for each experimental set. Ventral views. Right three panels: RNA in situ hybridization of mpx, runx1 and c-myb expression. For mpx WISH, n=38, 33 and 25. For runx1 WISH, n=38, 29 and 30. For c-myb WISH, n=31, 25 and 37. Listed sample sizes relate to each group shown from top to bottom. Scale bars: 100 μm.
